Four lakes formed recently in southern Egypt in an area that was
previously desert. Fed by unusually high levels of rainfall and water
overflowing from the Aswan High Dam on the Nile River, the first lake
appeared in 1998. The Aswan's overflowing waters are channeled through
an arroyo into a reservoir, as expected, but as the high rains have
continued, so has the overflow. Consequently, the reservoir has grown
in size and three more lakes have formed.
Authorities in Egypt estimate that, together, the lakes now hold about
700 billion cubic feet of water--one quarter the Nile's total water
supply. Scientist don't know whether or not the lakes will remain, or
will dry up within a few years.
